Cloudflare offers 10GB of free R2 storage. HA has a backup plugin for Cloudflare R2.
HA already has many plugins for doing voice processing locally or through other cloud providers (freely or cheaply)
A cloudflare tunnel would also give you direct access to WebRTC streams, just like being at home. HA Cloud just offers relay servers so you don't have to directly connect.
If you want to give HA money, go ahead but there's nothing truly compelling it offers that I couldn't get elsewhere for much less.
